Technical Field

The invention relates to a sealing tool for an oblique-mouth pipe in a cabin.

Background

Before the sectional piping system enters the sand room, various pipes need to be effectively sealed so as to ensure that sand pills do not enter the inside of the pipes. The conventional sealing methods (such as wooden plugs, blind plates and the like) cannot effectively seal the injection pipe.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides a sealing tool for an inclined opening pipe in a cabin, which can effectively seal an injection pipe, prevents foreign matters such as sand balls from entering the pipe, is simple to use, has strong universality and is suitable for sealing the pipe diameter of 22-168 mm.

In order to achieve the purpose, the technical scheme of the invention is to design a cabin inner inclined opening pipe sealing tool which comprises a shock-proof plate arranged on one side of a backer, wherein a blind plate for sealing an inner inclined opening pipe is arranged on one side, away from the backer, of the shock-proof plate, the blind plate is fixedly connected to the shock-proof plate through at least three bolts, and a sealing gasket is arranged between the blind plate and the pipe orifice of the inner inclined opening pipe; the impact-proof plate is arranged on the backer in a sliding manner; the impact-proof plate comprises a hard layer close to the backer and a soft layer close to the blind plate. A matched rubber is padded between the blind plate and the injection pipe. And (3) knocking a bolt diagonally, wherein the bolt props against the reverse acting force of the wall plate and the blind plate, so that the blind plate and the injection pipe opening form a seal through an eraser.

The further technical scheme is that a threaded hole matched with the bolt is formed in the hard layer, the soft layer is U-shaped, and an inserting groove used for inserting the soft layer is formed in one side of the hard layer. Therefore, the soft layer is used as a medium for primarily connecting the bolt and the impact-proof plate, the direction of a threaded hole in the impact-proof plate is not required to be considered (because the invention aims at the pipe orifice seal of the inclined-mouth pipe, the direction of the threaded hole in the hard layer of the impact-proof plate is obliquely arranged), the bolt can be screwed at first at will at the beginning, only the bolt is required to be connected with the soft layer, the angle of the blind plate (or the position of the impact-proof plate) is adjusted after the sealing gasket is basically abutted to the blind plate tightly, so that the bolt is aligned with the threaded hole in the impact-proof plate and then screwed tightly with force, and the soft layer can be replaced by pulling up the soft layer after multiple times of use.

The further technical scheme is that the blind plate is a square plate, the length of the blind plate is 268mm, the width of the blind plate is 168mm, the thickness of the blind plate is 12mm, nuts with the nominal diameter of 16mm are welded on the outer sides of four corners of the blind plate, four bolts are arranged, the nominal diameter of the bolts is 16mm, and the length of the bolts is 75 mm. The distance between the injection pipe and the plate surface is 30-50 mm, and the pipe diameter is 22-168 mm. In order to ensure the universality of the use, a square plate with the thickness of 12mm and the maximum cross section area as the reference is blanked, M16 nuts are welded at the four corners of the plate, and M16 75mm bolts are adopted.

The further technical scheme is that a sliding groove used for enabling the impact-proof plate to slide up and down is formed in the backer, a threaded hole communicated with the sliding groove is formed in the side face of the backer, and a stud used for propping the impact-proof plate is arranged in a manner of being matched with the threaded hole.

The further technical scheme is that the soft layer is made of rubber, and the hard layer is made of metal; and an aluminum foil layer is fixedly arranged at the U-shaped groove of the U-shaped soft layer. The quality and the life of the soft layer are increased by the arrangement of the aluminum foil layer.

The invention has the advantages and beneficial effects that: the injection pipe can be effectively plugged, foreign matters such as sand balls are prevented from entering the pipe, the use is simple, the universality is strong, and the injection pipe is suitable for sealing the pipe diameter of 22-168 mm. Therefore, the soft layer is used as a medium for primarily connecting the bolt and the impact-proof plate, the direction of a threaded hole in the impact-proof plate is not required to be considered (because the invention aims at the pipe orifice seal of the inclined-mouth pipe, the direction of the threaded hole in the hard layer of the impact-proof plate is obliquely arranged), the bolt can be screwed at first at will at the beginning, only the bolt is required to be connected with the soft layer, the angle of the blind plate (or the position of the impact-proof plate) is adjusted after the sealing gasket is basically abutted to the blind plate tightly, so that the bolt is aligned with the threaded hole in the impact-proof plate and then screwed tightly with force, and the soft layer can be replaced by pulling up the soft layer after multiple times of use. The distance between the injection pipe and the plate surface is 30-50 mm, and the pipe diameter is 22-168 mm. In order to ensure the universality of the use, a square plate with the thickness of 12mm and the maximum cross section area as the reference is blanked, M16 nuts are welded at the four corners of the plate, and M16 75mm bolts are adopted.
